Problem Set III: Energy Metabolism and Temperature 1) Assume the metabolic rate of a small frog is 25 ul O 2 /g · h at a temperature of 10 ºC. What are the metabolic rates of the frog at temperatures of 20, 30 and 40 ºC if the Q 10 is 2? What are the rates at these temperatures if the Q 10 is 2.5? 1.0? 2) The reaction rates for a process (units arbitrary) are given below for three different temperatures. (A) Calculate the Q 10 values for each temperature interval (i.e., 17-25; 25- 30). (B) Within which temperature interval is the reaction rate most sensitive to temperature change? Temperature, ºC Reaction Rate 17 100 25 175 30 300 3) If the reaction rate for a process is 5 units at 15 ºC, what would be the reaction rate at 20 ºC if the Q 10 for the temperature interval is 3.4? 4) The equation describing the relationship between rates of oxygen consumption and body mass in mammals is: V 02 = 0.676 M 0.75 where V 02 is liters of oxygen per hour and M is body mass in kilograms. Derive an equation which relates the rate of oxygen consumption
